Actually, the RedBoot in that package does replace the original code in
function (i.e. only RedBoot runs from reset). This is an artifact of how
the hardware is wired up on the board - there is a switch to decide how
the FLASH is mapped.
You should be able to take the at91/eb40 package and modify it to suit
your needs. Everything should be in there. Note however that the released
code is somewhat hardwired to that particular configuration. You may need
to adapt it to your hardware.
